Not really a Calculator

Just has lists of the most common conversions.

Developer Response ,

Metrebug is a unit conversion calculator. The list of common conversions is an added bonus that can be selected by tapping the "info" icon on the right side of each converter row. The calculator feature is selected by tapping either the converter type icon or name on the left side of each converter row. Hopefully this helps.

Not happy!

Developer Response ,

Sorry to hear you are having trouble using the app. It appears like you need to enter a number in the source value text field before you see any conversions. Detailed instructions are also provided in the bottom section of the main menu. If you need additional support, please tap Support & Feedback, which is also in the main menu, and I will be happy to assist you further.
